Abstract

S3 nerve root neuromodulation is becoming an accepted therapy for individuals afflicted with lower urinary tract symptoms, such as idiopathic urinary urge incontinence, frequency, urgency, and urinary retention, who fail current standard therapies. This patient population is difficult to treat, and this therapy offers an option that can restore quality of life to these individuals. While the precise pathophysiologic mechanisms underlying these voiding symptoms is unknown based on the physiology of bladder function, it is logical to conclude that they relate to some aberration of the neuromuscular apparatus of the bladder and/or its outlet (the urethra). These pathophysiologic defects are not overtly manifested outside the lower urinary tract because these patients routinely do not have any apparent neurologic deficits. The fact that S3 neuromodulation can clinically improve these lower urinary tract symptoms would support the notion that the neural regulation of the bladder is somehow altered in these patients. This paper presents a review of the current knowledge regarding sacral neuromodulation in treatment of non-neurogenic voiding dysfunction.

This paper, along with references [10] and [11], represents the modern clinical series of using S3 neuromodulation in treating idiopathic urinary urge incontinence, frequency-urgency syndrome, and nonobstructive retention. The investigators designed a robust clinical study (the design was identical in all three papers; the only difference was the inclusion criteria) utilizing randomization of controls (delayed neuromodulation group), standardized data collection sets, and well-defined treatment outcome parameters.

The mechanism of neuromodulation in altering the biochemical phenotype of the target organ is suggested. Modified approaches to neuromodulation may make this therapy easier and more acceptable to patients and clinicians.
